Marine Structure Projects

Xypex products play a key role in the waterproofing and protection of concrete against water penetration, chloride ion attack, cracking, carbonation, sulphate attack, Alkali Aggregate Reaction and freeze/thaw damage.

409 and 499 Illinois

San Francisco, California, USA

With an especially high water table at 8 feet below grade, the possibility of saltwater attack, and a garage design calling for two parking levels at 30-ft below grade, Xypex Admix C-1000 NF was specified to waterproof and protect the below-grade slabs and perimeter walls.

Al Khalifa Port and Industrial Zone

Dubai, United Arab Emirates

Anderson Point Port Facility

Port Hedland, Australia

This project will mine and export through the Anderson Point Port Facility, 45 million tonnes per annum (mtpa) of Iron ore to markets in Asia. Xypex C-Series is spec’d into all concrete elements of the berthing facility, to provide enduring protection for this vital asset. As of June 2011, Berths 1 & 2 are complete, with Berth 3 underway.

Australian Marine Complex

Perth, Australia

Approximately 1,000 m3 of precast product was treated with Xypex Admix C-5000 at a grade of 50 MPa. Besides enhancing durability, benefits of Xypex Admix C-5000 include ease of application into the concrete mix, workability with vertical pours and the long term benefits of the Xypex crystalline process.

Bremerton Tunnel

Bremerton, Washington, USA

The tunnel was to be built on a high water table and its entire length needed waterproofing; shoring of the walls would interfere with any barrier-type system; considerable rebar work was needed on the floor, thus raising the risk of damaging a membrane; and the ceiling would be covered with a 10-ft.-deep backfill making a membrane impractical to repair. Xypex Admix was the answer to all these concerns.

Rangali Island, Maldives

Dique de Carena Dry Dock

Puerto Belgrano, Argentina

Soletanche Bachy, renowned worldwide for their expertise in geotechnical and civil engineering, was retained as the engineering firm and contractor on this dry dock project. Xypex Concentrate and Patch'n Plug were specified and used to rehabilitate the concrete structure and will again be used on two smaller docks later in the year.

Esplanade Theatres on The Bay

Singapore

Xypex admixture treated concrete replaced the membrane assembly used in the first phase. During construction of the first phase Xypex was used extensively to fix leaking experienced in the membrane based secant wall assembly. Through the use of Xypex products and techniques the first phase was fully waterproofed.

Flinders Ports Berth 8 Outer Harbour Grain Wharf

Adelaide, Australia

Xypex Admix C-1000 NF was specified as the most suitable product to effectively protect the concrete structure from the harsh marine environment. Pile plugs, pile caps, rear ramp support walls, wharf beams, deck and ramps were all dosed with Admix C-1000 NF at a rate of 3.9 kg per meter.
